Abstract

Système d’électrolyseur haute température optimisé par dépression de l’alimentation en vapeur d’eau L’invention concerne un Système comprenant - un électrolyseur (1) à haute température (EHT), - une première ligne d'alimentation (2) de l'électrolyseur configurée pour alimenter l'électrolyseur (1) en vapeur d'eau, - une première ligne d'évacuation (4) de l'électrolyseur configurée pour évacuer depuis l'électrolyseur (1) du dihydrogène, - une deuxième ligne d'évacuation (3) de l'électrolyseur configurée pour évacuer depuis l'électrolyseur (1) du dioxygène, - un premier module d'échange thermique (5) configuré pour assurer un échange thermique entre la première ligne d'alimentation (2) en vapeur d'eau et la première ligne d'évacuation (4) du dihydrogène, - un générateur de vapeur(6) agencé sur la première ligne d'alimentation (2) en vapeur d'eau, en amont du premier module d'échange thermique (5), et configuré pour produire de la vapeur d'eau à partir d'eau liquide, caractérisé en ce que le système comprend un module de mise en dépression d'un tronçon (30) de la première ligne d'alimentation (2), le module comprenant un détendeur(28) et un compresseur (29), le détendeur (28) étant agencé, sur la première ligne d'alimentation (2) en vapeur d'eau, en amont du générateur de vapeur (6) et le compresseur (29) étant agencé, sur la première ligne d'alimentation (2) en vapeur d'eau, en aval du générateur de vapeur (6). La présente invention concerne le domaine de l'électrolyse de l'eau à haute température à oxyde solide (SOEC, acronyme anglais pour « Solid Oxide Electrolyte Cell ») et celui des piles à combustible à oxydes solides (SOFC, acronyme anglais pour « Solid Oxide Fuel Cell »). Elle trouve pour application particulièrement pour optimiser la consommation énergétique d'un système électrolyseur SOEC. Figure pour l’abrégé : Fig.1High-temperature electrolyser system optimized by depression of the water vapor supply The invention relates to a system comprising - a high-temperature (EHT) electrolyser (1), - a first supply line (2) of the electrolyser configured to supply the electrolyser (1) with steam, - a first evacuation line (4) of the electrolyser configured to evacuate dihydrogen from the electrolyser (1), - a second line of evacuation (3) of the electrolyser configured to evacuate from the electrolyser (1) oxygen, - a first heat exchange module (5) configured to ensure a heat exchange between the first steam supply line (2) of water and the first dihydrogen evacuation line (4), - a steam generator (6) arranged on the first steam supply line (2), upstream of the first heat exchange module (5), and configured to produce water vapor from liquid water, characterized in that the system comprises a module for creating a vacuum in a section (30) of the first supply line (2), the module comprising an expansion valve (28) and a compressor (29), the expansion valve (28) being arranged, on the first steam supply line (2), upstream of the steam generator (6) and the compressor (29) being arranged, on the first steam supply line (2), downstream of the steam generator (6). The present invention relates to the field of solid oxide high temperature water electrolysis (SOEC, English acronym for " Solid Oxide Electrolyte Cell ") and that of solid oxide fuel cells (SOFC, English acronym for " Solid Oxide Fuel Cell"). It finds application particularly in optimizing the energy consumption of a SOEC electrolyser system. Figure for abstract: Fig.1
